Extend the FeatureSource interface with new methods for configuration
handling. This enables easier on-the fly reconfiguration of the
feature sources. Further, it simplifies adding config support to feature
sources in the future. Stub methods are added to sources that do not
currently have any configurability.
The patch fixes some (corner) cases with the overrides (--options)
handling, too:
- Overrides were not applied if config file was missing or its parsing
failed
- Overrides for a certain source did not have effect if an empty config
for the source was specified in the config file. This was caused by
the first pass of parsing (config file) setting a nil pointer to the
source-specific config, effectively detaching it from the main config.
The second pass would then create a new instance of the source
specific config, but, this was not visible in the feature source, of
course.
Introduce a new scheme where features may have logical sub-components.
Rename sriov labels from the network source according to the new
pattern:
sriov -> sriov.capable
sriov-configured -> sriov.configured
Also, document this new labeling scheme in the README.

* Format main,fake,network go source to improve GoReportCard
Order of import changed in main.go and network.go,
missing ending newline added in fake.go
* Fixed simple golint suggestions in multiple files
Mostly about missing or incomplete comments
* Adding SR-IOV capability discovery to node-feature-discovery
* SR-IOV capability discovery in NFD : code update after PR review
- using hostnetwork instead of volume mount in file node-feature-discovery-job.json.template
- iterating through network interfaces that are "up" in sources.go
- inserting logs in sources.go
- change in feature source name from "netid" to "network" in sources.go, README.md and main.go
* Added code for labels sriov=true (sriov_totalvfs > 0) and sriov-configured=true (sriov_numvfs > 0)
* Code Refactored: Added Network package and network.go
